The ARPA Computer Network Working Group met at UCLA the evening of 
November 16, 1967. In attendance were: 
B. $oehm (RAND) 
G. Buck (UCSB) 
L. Kleinrock (UCLA) 
/L. Roberts (ARPA) 
E.' Shapiro (SRI) 
R. Taylor (ARPA) 
B, Wessler (ARPA) 
Three topics were discusse: 
(1) objectives of the Working Group (see attachment 1) 
(2) a report outline (see attachment 2) 
(3) functional characteristics (see attachment 3) 
Work assignments suggested by members of the group were: 
Report IMP Functional Char. 
Members of the group who can contribute to topics assigned to others 
were urged to assist the latter by contributing ideas, etc. Written 
material should be distributed to all members of the group as it 
becomes available. Wessler is to be called by all on or before 
November 30 to provide him with a progress report. A target date 
for completion of the draft report is still January 31, 1968.
